Definitions

  • a process for the catalytic hydrogenation of halogenated silanes or Germans are hydrogenated in the halogenated mono-, oligo- or polysilanes or -germane with hydrogenated Lewis acid-base pairs or partially hydrogenated and partially halogenated Lewis acid-base Pairs are hydrogenated with release of hydrogen halide and in particular with subsequent addition of H 2 and its heterolysis on the Lewis acid-base pairs.
  • the invention is based on the object, a method for the hydrogenation of silicon or germanium halides create a particularly high yield with a low proportion of by-products can be achieved.
  • Main group are halogenated with chlorine or fluorine.
  • the hydrogenation of the halogenated silane / Germans is performed upstream platoons with a temperature between -20 0 C and 200 0 C. Further, the hydrogenation of the halogenated silane / german is preferably carried out at a pressure between 0.05 MPa and 0.5 MPa.
  • the precipitating in a hydrogenation reactor as a solid Element-hydrogen compounds of IV as a solid Element-hydrogen compounds of IV.
  • Main group withdrawn through a take-off device at the bottom of the reactor.
  • Main group are preferably obtained via a take-off device.
  • the hydrogen halide formed in a reaction reactor is preferably expelled thermally and removed from the process via a valve.
  • the elimination of the halogen hydrogen is preferably carried out at temperatures between 100 0 C and 300 0 C.
  • Lewis acid-base pairs which can not form direct adducts due to their sterically hindered structure, can serve as catalysts for the heterolytic cleavage of H 2 .
  • Lewis acid and Lewis base may exist as separate compounds, but they may also be contained within a molecular compound.
  • the catalytically active compounds can be fixed on carrier bodies.

Abstract

La présente invention concerne un procédé d'hydratation catalytique de silanes halogénés ou de germanes halogénés, selon lequel des mono-, oligo-, ou polysilanes halogénés ou des mono-, oligo-, ou polygermanes halogénés sont hydratés ou partiellement hydratés avec des paires acide-base de Lewis hydratées, et les paires acide-base de Lewis partiellement halogénées sont à nouveau hydratées par adjonction d'halogénure d'hydrogène et en particulier par adjonction ultérieure de H<SUB>2</SUB> et hétérolyse au contact des paires acide-base de Lewis.
